JOINT-RING FOR ACETYLENE-GAS LAMPS.

Specification of Letters Patent.

Patented Nov. 5, 1907.

Application filed December 22.1906. Serial 110. 349,067-

To all whom it may concern:

Be it known that I, CHARLES W. BECK, a citizen of the United States, residing at Rockville Center, in the county of Queens and State of New York, have invented certain new and useful Improvements in Joint- Rings for Acetylene-Gas Lamps, of which the following is a specification, reference being had therein to the accompanying drawings, in which Figure 1 is a side elevation of the joint ring showing it in its released position; Fig. 2 a similar view showing the ring in its closed or clamping position; Fig. 3 a plan view of the ring; Figs. 4 and 5 detail views of the means for adjustably connecting together the ends of the two sections of the ring; Fig. 6 a vertical sectional view of a portion of an acetylene gas lamp; Fig. 7 a horizontal sectional view showing a modified form of the device for flexibly connecting the ends of the two sections of the clamping ring- Fig. 8 a side elevation thereof; Fig. 9 a vertical sectional view thereof; and Fig. 10 a hori zontal sectional view of a portion of the lamp showing a spring for expanding the clamping ring when said ring is released.

This invention relates generally, to means for connecting together two telescoping parts to form a gastight joint; and it relates, specifically, to means for detachably connecting together the upper and lower parts of an acetylene gas lamp of the type shown in my Patent Number 790,868, dated May 23d, 1905.

One of the main objects of the invention is to provide a connecting ring for lamps of the class shown in my said patent, by which the two parts of the lamp may be quickly and rigidly connected together.

Another object of the invention is to provide a clamping ring by which two telescoping parts may be drawn together with considerable force so that by the interpo sition of a flexible yielding gasket between the two parts a gas tight connection may be quickly made.

Other important objects and advantages of the invention will appear hereinafter.

Referring to the various parts by numerals, 1 desig nates the upper portion of the base or water holder of the lamp, and 2 the lower portion of the carbid holder or upper part of the lamp. The clamping ring is designed to connect these two parts together and to form a gas tight joint therebetween. The upper part ofthe base or water holder is contracted and is formed with an upward extending short cylindrical part 3 which is open at its upper and lower ends and through which access is had to the interior of the water holder. At the top of this cylindrical part 3 on the exterior thereof is formed an outward extending horizontal bead or flange 4 which is inwardly and downwardly inclined on its lower side to form an annular cam surface 5, the upper surface of said bead, where it joins the part 3, being substantially fiat and slightly below the upper edge of saidpart 3, as shown clearly in Fig. 6. The

lower end of the upper part 2 of the lamp is formed with a cylindrical part 6 which is slightly larger in'internal diameter than the diameter of the bead or flange 4, so that said part 6 may fit down over said bead, as shown clearly in Fig. 6, so that the part 3 telescopes within the part 6. This cylindrical part 6 at its upper and lower ends is provided with annular exterior beads 7 to form an annular channel 8. At the upper end of, and within, this cylindrical part 6 are secured two annular strips 9 and 10 which form an annular interior channel 11. Within this channel is secured a gasket or packing ring 12, said ring being provided with a depending annular part or member 13 which fits within the cylindrical part 3 of the base of the lamp, the main body of the gasket engaging the upper edge of said part 3 and bearing on the upper surface of the flange 4, as shown clearly in Fig. 6. The gasket is provided on its upper surface with an annular extension 14 which fits between the two parts 9 and 10 above the chamber 11, and serves to aid in holding the gasket in position in said channel 11. It will, of course, be understood that while 1 prefer to use this form of gasket, the connecting means will operate successfully with any suitable gasket.

In the channel 8 formed by the beads 7 is mounted a clamping ring 15. This ring is formed in two sections flexibly and adjustably connected together by means of a hinge plate 16 which is formed with an aperture 17 and with a longitudinal slot 18 and transverse ratchet teeth 19 on its inner surface adjoining the slot 18. One end of one section of the ring 15 is formed with an outward turned hook 20 which is adapted to engage in the aperture of the hinge plate; and the other section of the clamping ring is provided at one of its ends with a ratchet tooth or lug 21, which is adapted to engage the teeth 19 on the hinge plate. 'lo adjustably connect the hinge plate to one section of the connecting ring is screw 22 which is passed through the slot 18 of the hinge plate and threaded into the section of the connecting ring, as shown clearly in Figs. 4 and 5. By this means the clamping ring may be adjusted to slightly vary its diameter to compensate for the wear of the packing ring, it being, of course, obvious that when said ring has become worn the clamping ring must be made smaller in order to draw the packing ring or gasket down on the bead 4 and on the upper edge of the cylindrical part 3 of the base of the lamp.

The sections of the clamping ring are each provided through apertures 24 formed in the cylindrical part 6- of the upper part of the lamp, as shown clearly in Fig. 6. For the purpose of contracting and expanding the clamping ring to cause the clamping lugs to engage, or

be released from, the clamping flange, the two sections of the clamping ring are connected together by the link 1'5 and the lever 26. The link 25 is connected at one end to one section of the clamping ring and the lever 26 is pivoted at its end to the other section of the clamping ring, prelerably near its free end. One end of the link 25 is connected to the lever at a point beyond its pivot and between its pivot and the handle part thereof, said point of connection between the link and the lever being so arranged that when the lever is thrown down, as shown in Fig. 2, to contract the clamping ring and to thereby force inward the clamping lugs against the clamping flange, the center of said pivot will be below a horizontal line passing through the center of the pivot of the lever with its section of the clamping ring and the center of the pivot of the link 25 to its section of the clamping ring. The object of this is to utilize the outward pressure on the lugs, which tends toexpand the clamping ring, to hold the clamping means locked. In order to release the clamping means considerable upward pressure must be exerted on the end of the lever to throw the point of connection between the link and the lever above the point of connection between the lever and its section of the clamping ring. This is of great advantage as it prevents said ring being loosened accidentally. It will, oi course, be understood that by connecting the link 25 to the lever between its pivot and it-s :free end the clamping ring will be expanded when the lever is moved upward and will be contracted when the lever is moved downward to a position horizontally in line with the clamping ring sections.

The link 25 is provided along its upper edge with an inward extending flange 27 which is adapted to engage the upper edge of the lever 26 when said lever is in its lockedposition, as shown clearly in Figs. 2 and 3, to prevent the further downward movement of said lever; and the lever is provided at its. free end with a linger piece 28 by which it may be operated.

The parts are so proportioned, of course, that when the lever 26 is thrown up, as shown in Fig. 1, the clamping lugs will be moved outward sufficiently to release the clamping flange 4 and thereby permit the upper part of the lamp to be lifted off the base part or water holder.

By reason of the cam surface 5 of the bead under which the beveled part of the lugs engage, the lugs, when they are forced inward as described, will draw the upper part of the lamp down on the lower part thereof and cause the packing gasket 12 to be compressed over the edge of the part 3 and down on the bead 4, thereby securing an absolutely gas tight joint.

In Figs. 7, 8 and 9, a slightly different form of hinge plate is shown. In this construction the two portions of the clamping ring are formed with outward turned hooks 20 adapted to be engaged by the hinge plate 16. This plate is provided at its vertical edges with inturned hooks 16 which interlock with the hooks 2O on the clamping ring. The hinge plate is provided with an upper horizontal flange 16 and with the lower flange 16, this lower flange being bent under after the hinge plate has been carried down into engagement with the hooks on the ends of the clamping ring sections, to permanently connect said sections and the hinge plate.

If desired, the cylindrical part 6 of the upper section of the lamp may be provided with a flat spring 29 which will lie between said part 6 and the clamping ring to normally throw the sections oi said ring outward. This is oi advantage as it withdraws the lugs 23 from under the flange 4 when the clamp lever 26 is raised.

From the foregoing it will be seen that I provide a means {or clamping together the two members of an acetylene gas lamp which does not require any careful adjustment of one of said parts on the other. It is not necessary that the lugs 23 should engage the flange 5 at any particular point. This is oi great advantage in assembling the two parts.
